BACE1-AS promotes the synthesis of β-secretase in the brain of patients with AD. Amyloid plaques in the brain of patients with AD are linked to the illness. Plaques are formed by the successive breakdown of the APP via β-secretase (BACE1) and γ-secretase. In individuals with BACE1 deficiency, the mRNA is stabilized by binding to its antisense non-coding RNA (BACE1-AS). miRNAs, such as miR-34a-5p, miR-125b-5p, miR-15b, and miR-149, inhibit BACE1 expression, decrease amyloid accumulation, and ameliorate neuronal injury.
